GTX Titan …. now I’m confused

[Juan Salvo]

As a standalone card, with a seperate GUI card, and a full resolve license, the 690 still wins. For use as GUI and processing, or with a lite license the Titan will come out ahead.

Well have lots of choices. And maybe a new cubix champ.

ok, I get your point. But what makes the Titan a lesser dedicated GPU Card than the 690? I guess comparing 4gb of ram to 6gb is not the only factor in measuring performance.

I’m in the same boat. About to purchase 3x GTX 680 inside a Cubix and then this comes out.

Juan, I’m assuming you’ve not had a chance to test yet, but you seem to be knowledgeable about these things… in your opinion, would the Titan be a better option inside a Cubix running on OS X?

Alex – Cubix has not yet tested this GTX card with any of the Xpander models. I don’t anticipate any issues with using it, but keep this info in mind as you purchase products for use with Xpander. You might contact Mic Grover in Cubix Support (micg@cubix.com, ph 775-888-1000, ext 220) before making a decision one way or the other.

Looks like you’ll be able to optimize CUDA via software! Sounds interesting…

Quote from the article above:
“Tapping in to the full-speed FP64 CUDA cores requires opening the driver control panel, clicking the Manage 3D Settings link, scrolling down to the CUDA – Double precision line item, and selecting your GeForce GTX Titan card. This effectively disables GPU Boost, so you’d only want to toggle it on if you specifically needed to spin up the FP64 cores.

We can confirm the option unlocks GK110’s compute potential, but we cannot yet share our benchmark results. So, you’ll need to look out for those in a couple of days.”

Thanks Eric, appreciate the info.

I guess it’s safe to say, we’ll just have to wait for some hard facts from benchmarks and fellow DaVinci user experiences.

Well they cost double what a 4gb 680 does right? And unless you’re trying to do stereo 4k, I think we’re reaching the point where the CPU in the Mac is being slowed down by raw formats more than resolve needs gpu power. I mean after 3 x gtx 680 4gb it might be diminishing returns.

You think only in terms of Mac though. linux and windows boxes both can use multiple gpus, and can have significantly faster processors and busses. The Macs are just really freaking old. 🙁

Well Alex said OSx so I assumed Mac, but I guess it could hackintosh
